Off the top of my head of some easy to do, practical steps you can take;
Changing your passwords regularly. every 6 months to a year maximum.
Having a unique password for every website, especially sensitive ones like banks.
Install adblocker (ublock origin seems to be the favoured one) on chrome and firefox.
Use a credit card instead of a debit card.
take advantage of two factor authentication if the websites offer it.
Have antivirus software and run scans reguarly.
Use malwarebytes antimalware and adwcleaner to scan for adware and spyware.
Make sure your Windows or Mac is updated.
Don't use unsecure WiFi hotspots (airports,cafes etc), and if you must, use a VPN.
